Abstract
Hg3(SBr)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are five inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded to two S2- and three Br1- atoms to form distorted HgS2Br3 trigonal bipyramids that share corners with three HgS2Br4 octahedra, a cornercorner with one HgS2Br3 trigonal bipyramid, edges with three HgS2Br4 octahedra, and an edgeedge with one HgS2Br3 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 58–65°. There are one shorter (2.48 Å) and one longer (2.49 Å) Hg–S bond lengths. There are one shorter (2.83 Å) and two longer (3.30 Å) Hg–Br bond lengths. In the second Hg2+ site, Hg2+ is bonded to two equivalent S2- and four Br1- atoms to form distorted HgS2Br4 octahedra that share corners with four equivalent HgS2Br4 octahedra, corners with two equivalent HgS2Br3 trigonal bipyramids, edges with four HgS2Br4 octahedra, edges with two equivalent HgS2Br3 trigonal bipyramids, and faces with two equivalent HgS2Br4 octahedra. The corner-sharing octahedra tilt angles range from 2–11°. Both Hg–S bond lengths are 2.43 Å. There are two shorter (3.26 Å) and two longer (3.44 Å) Hg–Br bond lengths. In the third Hg2+ site, Hg2+ is bonded in a 5-coordinate geometry to twomore »
